, IMPROVEMENT IN WATER-METERS.

T0 ALL WHOM IT MAY GONCERN:

Be it known that I, GEORGE R. MooRuof the city of Lyons, in the county of Clinton, and State of Iowa, have invented a new and useful ,Machine for Measuring Running Water-#a Water-Meter; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification. i

Figure lis an end view, with one head removed, and thus shows endwise all the internal machinery of the meter.

Figure 2 is an end view when the head is in-its place.

Figure 3 is a vertical view'of the interna-l machinery.

Figure l is a. side view cfa kind of catch of: pawl, by which the ratchet-wheel is turned..

Figure 5 is given to show an additional plan for 'moving the valve, and

Figure 6 an additional plan for moving the ratchet-wheel.

Figsr and 6 are given simply as optionals.

Observe, now, that the space in the cylinder is divided into three apartments bysolid and stationary divisions, as follows: 1

Fig. 3, which is a vertical view of most of the internal machinery of Athe meter, consists, rst, of a plate, A, extending the whole length of the cylinder, and width also, where it is placed, which is about half way from the centre point of the diameterto the circumference below;` thus the cylinder is divided into two apartments; second, there is a cross-piece below the plate A, the location of which is indicated by the dotted lines b Z7, and which perfectly subdivides all that portion of the cylinder which is covered by theplate A.

Now, keeping in mind these three apartments of the meter, it will be seen that both the inlet c and the discharge-pipe, shown by dotted lines, d, are located in the heads of the cylinder alike, each of them below the plate A, so that no water can pass from the inlet to the outlet-pipe, without first passing up through the plate A, then down again through it on the other side of Z1 b. Therefore, the plate A has four openings, at least, (it may have many more,) o o o o. These are Water-ways, and two are upon each side of the-cross-section b b, and they nre alternately opened and closed by the valve B, which closes but two at a time, one on either side of b Z1, so that there is always one place open for the water to pass into the meter through A, and one for it topass out.

The valve B is operated by the forcing-plate C, which turns upon journals at the centre of the cylinder, and 'extends the entire length of it, and sweeps about half the circle. l I

The valve B and the forcing-plate C have between them the two operating-levers a a, and the operationv of moving the valves, and of measuring the water, is as follows:

First. let C be resting upon a at the right-hand side. The valve B will then be turned, so as to open the water-way towards the inlet-pipe, and on thatside of the-cross-section b b.

New, there is a solid partition, e, extending the whole length of the cylinder, and from the journals of C down to the plate A, so that the water has no way of escape butto push C over on to the opposite a, where it instantly changes the valve and opens the water-way under C towards the inlet-pipe, and closes the other. This alternating motion continues steadily; C passes over first to one a, and then to the other, and regularly alternates the valve B. i

But in case the water is drawn from the meter so slowly as to bring around upon a, on either side, so gently as not fullyto change the valve, then the springs (l yielding to the pressure upon them'until the adhesion of the valve upon lthe plate A is hvercome, and the valve started, the spring impels it to a quick motion, and it goes toits place. l

The reciprocating or alternating rotary motions of Omake it necessary, in connecting the journalf to the ordinary meter-movements and indexes, to use a ratchet-wheel, D, (or equivalent,) to secure a complete rotary motion. The ratchet-wheel may be operated by means of an elastic catch, as seen in iig. 4, E, or by an ordinary patvl, as seen Vin iig. 6, and moved by the eccentric, L.

Fig. 5 shows how the levers a a may be entirely dispensed with, by simply placing arms upon G itself.

This nueten may be regulated to suit any given index, simply by shortening or lengthening, as .the case.

may require, the sweep of the forcing-plate C, by the set-screws g y, or by other mechanical modes.

The valve, also, need not be confined to this mode of construetion. A direct movement will work just as well as a rotary one. y

I have thus given a. clear description of the principles embraced in the construction of the meter, and such merely mechanical changes as the manufacturer may prefer are not excluded.

I also regard this plan of a meter as entirely applicable for measuring gas.

Having thus fully described my invention, what I claim therein as'new, and desire to secure by Letters `Patent, is-

1. The water-Ways o o o 0 through the plate A, in the manner and for the purpose herein set forth.

2. l"lhe forcing-plate C, upon its journalsf, operated by the wateigisubstantially in the manner and for the purposes herein set forth. p

3. The springs d d, used in operating the valveB, substantially in the manner and for the purp'ose herein set forth.

4. The levers a a and regulating-screws gg, substantially in the manner and for the purpose herein set forth. i l

5. The dividing-plate e, substantially in the rnannei and for the purpose herein set forth..
